In addition to its use within HTTP, one of the common mailbox formats
also uses Content-Length: to hold the number of octets in the message.
Systems that use this mailbox format also rewrite any existing
content-length: header before storing the message into the mailbox to
have the correct number of octets.
A different header is definitely in order.
People should also be aware of RFC 2076, Common Internet Message Header
Fields. (It's currently being updated as
draft-palme-mailext-headers-02.txt.) Any proposals for new message
headers should be checked against the lists in there to see if they're
already being used somewhere else.
